On the menu are plenty of cheap goodies to discover—fried yuca, stuffed poblano peppers, sweet plantain pockets—but what brings this place buzz are the pupusas. Mitt-sized tortillas made with corn or rice flour, pupusas maintain both the floppiness of a pancake and the tough chew of pita bread. They are perfectly round, and at Guanaco's come stuffed with a pasty chicharron (pork) or chicken and a variety of veggies: spinach, ayote (zucchini), jalapenos, refried beans. Mix and match ingredients, have them all, sample just one—it's your choice—just be sure to order yours with cheese and the loroco, a tropical herb.
